The shorter markcorrect relation to each other. Saidpositioning ing members 16 alternate with said longer memform 1-8 ispurposely made shorter in height than bers 14 and their heads aredirectly in front of the racket 21 to be marked, so the operator can 11oered at the sides thereof with a hardened steel band 13. The shape ofthe cam is determined 70 'adapted to be directly actuated by said cam, a

readily see to line up the racket with saidguide marks 20 and 22opposite each other.

Said positioning form 18 is supported by a table 25 in which a recess 26is cut to receive said form 18 and prevent any sidewise movement. Screws27 hold said form 18 to said table 25 as shown in Figure 3 of thedrawings. The cam 12 extends through an opening in said table 25, andthe racket 21 to be marked rests on the top thereof. y l y To actuatesaid cam upwardly any suitable and well known means may be employed. Themechanism I have shown consists of a flange 28 which is held by screws29 to the under side of said cam 12, into which flange the upper end ofan upright member or vertical lever 30 screws, the lower end screwinginto a lug 31. A forked, horizontal lever 32 is fastened to said lug 31Vby a pin 33 which extends through said lug 31 and forked end of saidlever 32, said pin being held in place by a cotter pin 34. A standard 35is forked at one end about said lever 32 by means of a pin 36 whichserves as a pivot and which is held in place by a cotter pin 37. At theend of said actuating lever 32 a foot treadle 38 is formed, downwardpressure on which Vraises said lever 32 and the other movable parts towhich said cam 12 is connected, forcing said cam upwardly and saidmarking members outwardly.

Fastened to said standard 35 is a stop member 40 which is recessed toreceive a rubber bumper 4l on said lever 32,'which parts 40 and 41 limitthe downward movement of said cam 12, and determine the normal positionthereof.

Said standard 35 is fastened to the floor 42, and a coil spring 43 whichis fastened around said pin 33 at oneend is held tosaid floor 42 by aneye bolt 44 imbedded in said floor. Said spring 43 insures the immediatereturn of the cam to normal position when pressure upon said foo-t Atreadle 38 is released.
